FRT-1与WR-1用于皮革防水加脂的研究

Study on Using Retanning Fatliquor FRT 1 and Waterproof Fatliquor WR 1 to the Waterproof Fatliquoring of Leather

ＲＴ１复鞣加脂剂与ＷＲ１防水加脂剂配伍用于铬鞣革的防水加脂具有协同效应，铬锆铝多金属盐联合固定得当，所得皮革的防水性明显高于单一铬盐固定。上述现象被认为与防水材料或固定材料之间的性能互补有关。随着革坯干燥时间的延长，皮革防水性有所提高。表５。

Abstract Using Retanning Fatliquor FRT 1 and Waterproof Fatliquor WR 1 together to the waterproof fatliquoring of chrome leather,the apparent synergistic effect was observed,and the waterproofness of the leathers fixed with some kinds of salts composed of chrome,zirconium and aluminium were higher apparently than that of the chrome salts alone.It results from complementation of these hydrophobic or metal materials in property.The waterproofness increased slightly with lengthening drying time of the leather in crust.
